MIT I/O Brush

I/O Brush is a new drawing tool to explore colors, textures, and movements found in everyday materials by "picking up" and drawing with them. I/O Brush looks like a regular physical paintbrush but has a small video camera with lights and touch sensors embedded inside. Outside of the drawing canvas, the brush can pick up color, texture, and movement of a brushed surface. On the canvas, artists can draw with the special "ink" they just picked up from their immediate environment.

Discussion

Sorry, but I think the tool itself is quite pointless. I just don't see any pracical use for it. Its just a digital camera that sends information directly to a computer and it is screened on usual digital board...
